Anagrus nilaparvatae (Hymenoptera: Mymanidae), is an egg parasitoid of the rice planthopper, Nilaparvata
lugens. In the current study, a seven generation bioassay was used to test for host-mediated effects of
transgenic cry2Aa rice (T2A-1) on this parasitoid. When A. nilaparvatae parasitized the eggs of N. lugens
reared on either Bt or non-Bt rice, there were no differences in survival, development time, longevity,
sex ratio or fecundity over seven generations. In addition, direct exposure to a high dosage of Cry2Aa
had no adverse effects on the survival or fecundity of A. nilaparvatae adults. Cry2Aa protein could not
be detected in the eggs of N. lugens or in the adults of A. nilaparvatae parasitizing eggs of N. lugens feeding
on Bt rice. These results indicate that A. nilaparvatae are not sensitive to Cry2Aa protein at the tested concentration
and there were no detrimental effects on any life-table parameters in our study.
